Abstract (en)
[origin: EP2346148A1] The drive (1) has a set of wound coils coaxially arranged to each other. A sensor (10) e.g. optical sensor, detects relative movement of a winding system and a magnet system (3), detects a relative position of the winding and magnet systems, and scans a bar ruler (18) mounted on an outer circumference of the magnet system. The magnet system is radially arranged in an interior of the winding system, and the bar ruler circumferentially extends over a portion of the circumference of the magnet system, where coils of the winding system include a radial bulge for holding the bar ruler. The sensor is selected from an optical sensor, a capacitive sensor and an inductive sensor.
